i know on most inport you can take that lil screen thats in the tb out and it help with like a 2-5 hp increase, but is this ok to to with our cars?

 

The 'screen' is supposed to help straighten out the air flow before it travels over your MAS resulting in a more 'consistant' reading of the airflow. I've run serveral months (all summer) with it removed and it does seem to help throttle response a bit.
